Pipe bender Kata - Quality OK!

The roofing structures of the arcuate and dome-shaped shaped were combined with the advent of flexible materials for the roofs. It is all known polycarbonate, soft roof, Various plastics with filling, flexible slate and professional flooring. There was a need and the ability to collect light and portable structures, roofs over trading pavilions, roofs over pools and canopies. What can be easier, bend the profile pipes in the arc on the pipe bender and attach a cell or monolithic polycarbonate to them.

I want to tell you more about the popular pipe bending machine "Kachka" for the profile and round tube, which is suitable for many works and performs almost all the necessary operations. Worked it out for small business and blacksmith workshops. I note that the pipe bender is compact and heavy. Its weight in a pack of 45 kilograms. Dimensions: 450x450x540 mm. You can't tell this photo, it looks attractive and even beautiful. The entire body of the pipe-bending is made in such a way that installing it on the table and screwing it to the table with four bolts (not included) through the base holes, you can immediately begin work.

What work can be done on the pipe bender "Kata"? It is possible to bend profile pipes 15, 20, 25, 30, 40, 50 mm and even 60x30 mm in the arc. Most often arc bent, which are subsequently used for greenhouses, canopies, visors, fences, arbors, pergola and other complex non-rectilinear structures.

On the pipe bender rollers for rolling profile pipe Are on the drive axes. Shafts are planted on bearings. The shafts have spars and chain transmission. If you rotate the handle, the rotation is transmitted to all axes, so to speak "all-wheel drive." Twist easier and the slipping pipe is almost excluded. In addition, a shallow notch is applied on the rollers, which provides an additional adhesion of rolling pipes with rollers.

This pipe bender can be easily remand into electromechanical.

Another bundle includes rollers for a round tube. Rollers under pipes with a diameter of 20, 25, 30 mm. Rolling the round tube is easily and the walls remain smooth without dents and corrugations.

You can work with a strip of the maximum 40x10 mm. The band on these rollers is hired perfectly. When I needed hoops with a diameter of 1 meter from the band 30x4 mm, I made them easily. The strip on the edge is rolled on the external roller, which are included with the pipe bend. You can maximize with a 30x4 mm strip.

We spent the tests revealed good performance of the pipe-bend and the high quality of the execution of individual elements. Simple I. reliable design. Katch - Quality OK!

The maintenance of the pipe-bending is not complicated. You need to periodically lubric the screw of the presser roller and the asterisk. Suitable any lubricant, you can "Litol".

To work with pipes or corners, a special machine is required, called pipe bender. A similar design allows bending metal elements to a given angle. If necessary, you can make professional pipe bender with your own hands, which is used in a wide variety of industries. Unlike the industrial version of the execution, home-made pipe bending is much cheaper. When conducting work, you can use fir-handed materials, which will lower the cost of the structure. Consider how to make pipe bender do it yourself at home.

Trubbibe device

There is just a huge amount different species The device under consideration. Before working on its creation, it is necessary to develop a drawing of a pipe bending or download it on the Internet.

Pipe bender for a round tube with your own hands can be made when taking into account the following features of its device:

1. Run-in A similar pipe bending machine is characterized by the fact that one end of the workpiece is fixed, and a fixed pattern is used for bending. Officon is carried out when the clamping rollers are applied. This scheme of manual pipe bending is used for many years.
2. Winding. Special pipe bender for aluminum pipes It is characterized by the fact that the workpiece is pressed against the movable pattern, which is used by the roller. The broach is carried out between the roller in motion and special emphasis. As a rule, the drive is electrical, since the required rate of the accompanying force is quite high.
3. Arblet design. This scheme is represented by a combination of two fixed rollers, as well as a movable template. The effort is transmitted to the workpiece through the movable template, which is located between two rollers. By controlling the movement of the rolling element, the most suitable bend angle is selected. It should be borne in mind that the Puppon Pubbier, which serves as a template, can have a different shape.
4. Rolling or rolling. In this case, the scheme is represented by a device with three rollers, two of which are supporting and one movable. The bend radius is regulated by changing the position of the central roller. It should be borne in mind that such a device is considered universal, since the bending radius can be adjusted in a sufficiently large range. The size of the pipe-bender of this type is relatively small, homemade design May be compact.

Choosing the most appropriate design for homemade manufactureIt should be borne in mind that an embodiment that works on the principle of the rolling is often produced in an industrial method due to the complexity of the high complexity of the main mechanisms. The arbalt method of bending today is extremely rare, as it has one essential drawback: the pressure is concentrated on the top of the template. When applying the arbalt machine, there is a possibility of a significant reduction in the thickness of the pipe wall, as well as its rupture. It is not recommended to use a similar device for flexible thin-walled blanks.

Most of all got the distribution of the design that works on the rolling principle. It is practically devoid of all the above deficiencies, it has relatively small sizes, can be portable, it is possible to adjust the angle of bending.

Homemade machine can have the most various design. When choosing a type, the attention is paid to which radius should be obtained. Most important parameters Billets that can affect the choice of a suitable design, the thickness of the pipe walls and its diametrical size are considered.

Types of pipe bending

The design under consideration can be classified by a fairly large number of features. For sale there are universal versions, as well as for narrow-controlled use. The device varies on the following features:

1. By type drive. An important element of the design can be called a drive that is hydraulic, electric, manual or electro-hydraulic. Recently, the larger distribution was obtained by an electric drive, as it is compact and very efficient. Hydraulic is greater efficient, but it is folded in operation, it takes a lot of free space and requires periodic service. Manual pipe bender is characterized by the presence of a mechanism that significantly increases the applied force. If we consider homemade versions, then they make manual pipe bending with your own hands. In addition, you can create with your own electrically driven pipe bender. But the hydraulic version of the performance is practically not made independently.
2. Classification is carried out in the degree of mobility. Allocate stationary and portable design options. In most cases, the universal manual pipe beggage is performed as a portable design. Homemade pipe bending for a round tube can be attached to the base in various ways. It should be borne in mind that during the performance of the work, part of the voltage occurred is on the basis. Therefore, when creating homemade option Performances need to ensure reliable fixation of the device.
3. According to the method of exposure to the workpiece - the main sign of the classification. For example, a cross-type pipe bender has its own special design, which is suitable for flexible metal or metal-plastic pipe. In addition, it is distinguished by a design that works on the principle of running, winding or rolled products.

Pipe bender homemade for metal pipes Maybe itself of different typesBut most often create a mechanical type when, due to the special design, the transmitted force increases several times.

Instructions for the manufacture of pipe bending

Recently, a rather great distribution received a question how to make pipe bending with your own hands. Such equipment is required when adjusting the production activity of the most different type. The simplest pipe bender with their own hands has a template design type. This is due to the fact that the rollers for pipe-bender do it yourself quite difficult.

Considering the template tube bending for a round tube. Note the following moments:

1. In the manufacture of structures, a tree array is quite often used. Due to this, work is significantly simplified and costs are reduced. However, it is worth considering that low strength and rigidity of the tree determines the use of such a machine only for aluminum bending, which has high plasticity.
2. Applied wooden barber Must have dimensions that are larger than the diameter of the workpiece processed.
3. The template must have a radius that will correspond to the bending radius. In order to simplify the process in the central part of the surface, which comes into contact with the workpiece, a small groove is created.
4. For convenience, two handles are created that have a metal fastening.
5. Creating pipe bender at home, it should be attached to a solid base, and with back side Install the focus.

An important point we call that the design under consideration is most used to be flexible for a large diameter. In addition, the shoe for pipe-bender of this type is not required, the load is distributed evenly, which allows the processing of thin-walled blanks.

You can make pipe bender with your own hands on other drawings. Before choosing the most suitable design, you should consider how it will often be work, for what kind of billets is made by the machine, how popular production will be. The design of the template type is characterized by quite large sizes, however, it is enough to carry out carpentry work, the materials used have a low cost.

The most complex design is the homemade tube-type roller type. In this case, the clamping roller is applied to transmit effort. In the manufacture of the design can use metal and wood, it all depends on how much it must be mobile and for what effort is designed.

The following points can be attributed to the features of this design:

1. For pipes manufactured from soft materials, To a greater extent, a tree is suitable as the main material. It can be used in the manufacture of a roller. For steel pipes We will have to use metal, since the amount of the transmitted effort will be significant. If you wish, the rollers can be purchased or made with your own hands at home.
2. Features of the design determine the presence of a moving and fixed roller. At the same time, a P-shaped holder is located in the central part.
3. The bending radius depends largely on the size of the applied rollers. Nominable Therefore, the movable roller must be quickly dismantled if necessary to set an embodiment with another diameter.
4. The installed holder should also be able to rotate.
5. The handle is mounted on the installed holder, with the rotation of which the force will be transmitted. It should be borne in mind that the handle acts as a lever. That is why it depends on its length, what an effort can be transferred.

A similar machine is suitable for the production of large parties, as rollers for pipe bending make with their own hands quite difficult. The device is suitable for working with pipes round cross section.

A common question can be called how difficulty is the manufacture of such a mechanism. When using a bending machine of this type, the following points should be considered:

1. To begin with, it is necessary to study the drawing or photos of the equipment under consideration. Only understanding with the principle of his work, you can create effective equipment with a wide range of use.
2. The main elements of this design is a relatively small amount. An example can be called two pulleys that can be made of wood or steel, frame with a lever and a pressure roller. It is quite important to create a reliable basis that will take part of the accomplished effort.

The principle of operation is quite simple:

1. The billet is placed in a stuffing roller's groove.
2. The pipe is fixed in the desired position with a clamp.
3. With the help of the lever, the workpiece is wrapped around the template, which also uses a roller of a certain diameter.

In order to significantly increase the efficiency of the design, an electrical drive can be applied. However, it should be borne in mind that with an electrical drive, it is rather difficult to monitor the diameter of the roundabout. In addition, the installed electric motor must transmit rotation through a lower drive, since the rolling speed of the roller is small. To do this, install a gearbox or clinorem.

Arblet pipe bending

A brightly unusual design has an arbal type machine. He got its name due to similar features with medieval weapons. Arblet pipe bending has the following features:

1. The basis of the structure is represented by the frame that can be made when applying corners and a schuleler. The connection of all elements is carried out when welding, the detachable methods are not recommended to be applied, since the resulting design must have high rigidity.
2. After creating a frame, a fastening of two rollers is carried out.
3. The homemade version of the execution can be described in that the force is transmitted directly through the jack of mechanical type. For the pipe of a small diameter of the pressure being created should be quite enough. The transfer of force is carried out through a shoe manufactured from durable metal with a low plasticity.

The pipe bender of the arbal type is more suitable for the billets of the circular section. This is due to the fact that the product with another cross section can be strongly deformed at pressure.

Hydraulic pipe bending

Making a pipe bending machine with your own hands, should determine what kind of drive will be. In most cases, homemade versions have manual drive, as it is easy to manufacture and costs cheaply. However, such a design cannot work with the billets that are manufactured when using rigid metals. Hydraulic pipe bender allows you to work with large diameter blanks and with a substantial wall thickness, however, the design is quite complex in execution and has many features.

Machining machine for a round tube with hydraulic drive should be considered the following points:

1. The transmission of effort is carried out through the working fluid, which is used or water. All highways must have a high degree of tightness, as well as to be calculated for a certain pressure.
2. Compressor can be used to create pressure.
3. The pressure is transmitted to the working body through the hydraulic cylinder.

Pipe bender for metal-plastic pipes with their own hydraulic drive hands can have the most different design. An important element in this case is exactly the drive that allows you to automate the process of bending and increase the scope of the device.

Pipe bender from jackt

Most often, manufacturing home-made pipe bending, a jack is used as the main element. It happens a few types. The jack itself is initially manufactured in order to increase and concentrate the accompanying effort, due to which the design can lift heavy mechanisms, for example, cars.

Homemade tube bending from the jack, as a rule, has a fairly simple design:

1. The billet is clamped between two fixed rollers.
2. The force is transmitted to the gap between the rollers.
3. The distance between fixed rollers largely determines the radius of the flexible and the value of the required effort to obtain a certain angle.

As previously noted, an arbal type pipe bender can be made when applying a jack.

In conclusion, we note that almost any device is a relatively simple machine, which by distributing the attached efforts to bend pipes and other billets of this type. It is often used to flexing products manufactured when using color alloys and steel. The industrial design of the design is bypassing homemade, as a rule, according to the degree of automation of the process. However, the cost of industrial pipe bending can exceed several tens of times the costs associated with the production of self-made option. That is why for household use or small-scale production is more suitable for homemade pipe bending.

The pipe bender for a round tube is actively used when laying water supply, heating and sewage networks. Also, the masters use them to create decorative elements. For work, it is not necessary to preheat the material, including steel blanks.

By type of drive tube can be:

• Manual is a rolling mechanical fader for household tasks and periodic operation. One of the advantages is an attractive price.
• Hydraulic - hydraulic engine allows you to increase the pressure without applying additional physical efforts. Suitable for thick-walled profile pipes.
• Electromechanical - industrial option for mass production. Electrical drive allows you to significantly speed up workflows.

How much is the bending machine, depends on its characteristics and functional. To choose a suitable model, call our manager - they will help to make a choice and will answer all questions! Possible sale in installments.

To perform construction and mounting workespecially when it comes to pipelines, often pipes are required with various angle Bend, and the use of fittings may not be justified at all.

Flexible pipes in such cases is carried out using pipe bend. These and portable, industrial and home use.

Device and principle of manual pipe bending

Hand-made pipe bender in design and the principle of operation is quite simple, so the homemade craftsman may well conduct with its manufacture own. The main elements in any device for flexible pipes are the pressure plate. It presses a special mechanism with a certain effort, and it transmits an effort on the pipe processed.

As a pressure mechanism, both an electric motor or a hydraulic pump and a spring with retainers are used.

To perform bending, the corrugation is installed between the pressure plate and several shafts that perform the function of stabilizers. Also, with the help of the shafts, you can adjust the bending radius, since their position is adjusted.

So, for the bend of the pipes on a small radius, the shafts are located close enough to each other, and if it is necessary to increase the radius, then they are transferred away from each other.

For the bending of the round tube on the pipe bending the shapes are installed in the shape of a crescent.

Manual device

The homemade hand-made pipe bender, with which the flexible round pipes are carried out, is two flowing pulley, one of which is fixed motionless, and the second rotates around the first diameter of the processed pipe. The principle of his work is simple: Between the two pulleys, the pipe is laid and by rotating the movable pulley bending a round tube to the desired angle.

Manual pipe bender in the hands of a skilled host may be needed at any time, because it is thorough to fit it thoroughly, so that it can be bent pipes of various diameters.

For such a design, two triple pulley will be required instead of single: one pair will be used for flexible pipes 1/2 ", the other is for pipe 3/4", and one for inch pipes.

In the market, it is unlikely to buy such devices, so they will need to be ordered in a turning workshop. At the ends of the shafts, an outlet is made, which coincides with the half-diameter of corrugations.

Another important momentTo be taken into account in the manufacture of shafts - the stationary pulley in size should be minimal, since it depends on the minimum possible radius of the product bending. The optimal size of the movable shaft exceeds the diameter of the stationary.

Pipe bender design sequence

So, now directly about the stages of the work that are performed independently:

• after the shafts are ordered, proceed to the manufacture of the base under home-made pipe bending. A thick metal plate (at least 10 mm) square shape is suitable for it. To mount the base to the table, you need to drill four holes in the corners of the plate, or to welcome metallic pillarclosed in the floor;
• in the center of the plate using welding fasten the pin of the same diameter as a small triple shaft;
• the next stage It is necessary to make a rotary mechanism. For this, three metal plates are welded in the form of the letter P (width of the plates of more than 50 mm), and the height of the structure depends on the diameters of a large and small shaft: a completely movable pulley and half of stationary should fit in this altitude;
• to mount the shafts, you will need to drill a few holes. The legs of the letter P are from each other, slightly greater than the height of the shafts. To the upper stack of the design, a handle is welded, a length of about 25 cm, to which the tube-lever is subsequently worn;
• the large pin is mounted primarily and is fixed with plintes behind the plate in the form of the letter P, and the small shaft is put on with the whole design;
• for the hardware stopper equipment, another pin installed vertically welds. He will serve as a stop.

The second method is similar to the previous one, only Metal hooks are used as a template, which secure on top of the plywood sheet along the alleged bend. The advantage of this design is that the hooks can be rearranged to change the pipe radius.

Advantages and disadvantages of manual pipe bending

The main advantages of manual devices:

1. It has small overall dimensions and weighing. Flexible pipes with them are possible almost anywhere: in the workshop, on cottage plot, in the garage or on the construction site. As a rule, the need for a pipe bender for round pipes occurs in those places where engineering systems are paved.
2. Another advantage is that with the help of such devices, flexible pipes made of soft metal or.
3. Manual aggregate is quite mobile: if necessary, it can easily be transferred to any place.
4. Even the most inexperienced user will cope with the work on the handbreaker: the principle of his work is so simple that it is simply impossible not to understand it.

However, along with advantages, there are also disadvantages of using such an instrument. One of the most important: no ability to generate a large diameter pipe. Also predica will be flexible thick-walled.
